Abstract: Disclosed herein is a foam composition comprising an olefin copolymer that comprises ethylene and an α-olefin or propylene and an α-olefin; an ionomer that comprises copolymer of ethylene and a carboxylic acid; where the ionomer is neutralized with a metal ion; a crosslinking agent; and a blowing agent. Disclosed herein is a method of manufacturing a foam composition comprising blending together an olefin copolymer that comprises ethylene and an α-olefin or propylene and an α-olefin; an ionomer that comprises copolymer of ethylene and a carboxylic acid; where the ionomer is neutralized with a metal ion; a crosslinking agent; and a blowing agent to form the foam composition; heating the composition to activate the blowing agent; and crosslinking the composition.
